We aimed to identify risk factors for cholecystitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective, single\u2010center study of 280 patients (336 stents) who received endoscopic SEMS placement between May 2005 and April 2016. Clinical records were used to perform risk factor analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 336 SEMS placement procedures, 25 (7.4%) led to development of cholecystitis. Logistic regression analysis revealed three independent risk factors: covered SEMS (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.014), tumor involvement to the cystic duct (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.017), and presence of gallstones (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.022). Median time to cholecystitis onset was shorter with covered SEMS than with uncovered SEMS (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.034), and in patients with pancreatic cancer compared to those with other cancers (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.001). Severe cholecystitis developed within 30\u00a0days after covered SEMS placement in three patients with pancreatic cancer without tumor involvement to the cystic duct.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Use of covered SEMS might be a risk factor for cholecystitis onset within 30\u00a0days after placement.
